MAX7219 displaying characters OK

So I can display some characters using MAX7219.  Next step is to display the 8x8 LED matrix.


    ...

    // *** Display 8 digits ***

    displayOneDigit(txBuffer, xferConfig, spiChannelNumber, DIGIT_ADDR_7, CHAR_H);
    displayOneDigit(txBuffer, xferConfig, spiChannelNumber, DIGIT_ADDR_6, CHAR_E);
    displayOneDigit(txBuffer, xferConfig, spiChannelNumber, DIGIT_ADDR_5, CHAR_L);
    displayOneDigit(txBuffer, xferConfig, spiChannelNumber, DIGIT_ADDR_4, CHAR_P);
    displayOneDigit(txBuffer, xferConfig, spiChannelNumber, DIGIT_ADDR_3, CHAR_BLANK);
    displayOneDigit(txBuffer, xferConfig, spiChannelNumber, DIGIT_ADDR_2, CHAR_BLANK);
    displayOneDigit(txBuffer, xferConfig, spiChannelNumber, DIGIT_ADDR_1, DIGIT_0);
    displayOneDigit(txBuffer, xferConfig, spiChannelNumber, DIGIT_ADDR_0, DIGIT_1);
    displayOneDigit(txBuffer, xferConfig, spiChannelNumber, OPERATION_ADDR, NORMAL);
